feat: GraphDB prefix methods, skill verification & reputation endpoints

- Add subjects_with_prefix() and delete_by_subject_prefix() to GraphDB
- Re-export TripleBuilder from aingle_graph
- Add skill verification REST endpoints (validate, sandbox CRUD)
- Add reputation REST endpoints (consistency, batch-verify)
- Add SandboxManager to Cortex state
- Switch cortex deps to workspace path (graph, logic, zk, titans)
- Bump aingle_graph 0.2.1, aingle_cortex 0.2.4
